Consider the formation of HI (g) from H2 (g) and I2 (g).
H2 (g) + I2 (g) ⇌ 2HI (g)
For this reaction, the equilibrium constant, K = 98, at 333°C, whereas K = 62.5, at 527°C.
Determine the value of S° for I2 (g) at 527°C.
Consider the following reaction,
PCl3 (g) + Cl2 (g) ⇌ PCl5 (g)
where ΔH°f for PCl3 (g) = −287.0 kJ/mol and ΔH°f for PCl5 (g) = −374.9 kJ/mol.
Given that Kp = 0.555 bar−1 at 250.0 °C, calculate the value of Kp at 400.0 °C.
2. N2(g) + 3 H2(g) =NH3(g)
